My friend, who has no internet access, suggested I try to get your attentions on this question, thanks:
I have been helping a friend rebuild his 480B transaxle assembly and we have the following issue: we have it about 95% back together and discovered that we didn"t install the wear sleeve on the back end of the mainshaft before installing the seal carrier in the front end of the differential case. Question; what is the least amount of teardown that could be reasonably done to remove that carrier so that the wear sleeve could be installed?
It looks to me like the differential side gears could be removed with the carrier plates, so the seals would not be damaged, and this would allow the ring gear to drop low enough or flop sideways enough to let the seal carrier to get past it. Let me know if this is not so or if there is an even easier way to do it.
On a related note, the needle bearing and seal in the back-end of that seal carrier seem to be sized for an 1-1/4" shaft but the PTO shaft is 1" at that section, what"s up with that?
Please have a little sympathy on me since this tractor was received in an improper condition, i.e. the tractor came with PTO yet that housing was not even installed causing all sorts of other issues as well.
Thanks for any help you can give on this matter.
